Can vacuum glass food containers be put in the freezer?
Vacuum glass food containers are a modern food storage tool, which is characterized by good fresh-keeping performance and high temperature resistance. However, many people have doubts about whether vacuum glass food containers can be placed in the refrigerator to refrigerate food. This article will discuss this issue and give relevant answers.First of all, from the perspective of material properties, vacuum glass food containers are composed of two or more layers of glass, with a vacuum or inert gas-filled gap in the middle. This structural design gives it good thermal insulation performance. When the outside temperature is lower than the internal temperature, the heat in the container is not easy to dissipate through the vacuum layer, thereby slowing down the speed of heat exchange. ...
